Yes, he is nearing the career L record.
But he is also tied top 10 in the W column with Bill "You Are What Your Record Says You Are" Parcells. If LA were to win 28 more games in the next three seasons BEFORE moving into Kroenke World, that would tie him at 200 with Marty Schottenheimer, just outside the top 5. Belichick the only ACTIVE HC with more (226). Extending just past the top 30 winningest HCs, the next closest active are Andy Reid (9 wins back), John Fox (46 wins back) and Marvin Lewis (58 wins back) relative to Fisher's 172.
